-To aZ whom it may concern:

Be it known that l, CHARLES E. MCNA luARA, a. citizen oi' the UnitedStates, residing at Duluth, in the county of St. Louis and State ofMinnesota, have invented. certain new and useful Inun'ovcments inMarginlndicating Devices for 'lype-lVrit-ing Ma chines and I do herebydeclare the following to he a full, clear, and exact-description ofthe-invention, such as will enable others skilled in the art to whichitappertains to make and use the same.

i My invention relates to margin indicators for. tfvpewriting machinesand has i or its object the provision of a convenient device forindicating the available writing space between the top and bottom of thepage to be Written.

It consists of the constructions combinations and arrangements of partshereinafter describecand claimed. I

In the drawings, Figure 1, is a front elevntion of one form of my saidinvention. Fig. 2, is an enlarged central vertical section of the same.l ig. 3, is a rear elevation ol the same. Fig. 4 is a perspective view'of it presser device forming part ol one l O llll of said invention.Fig. 5, is aside elevation of. said form 01 said invention showing partsof the carriage of a. typewriting machine upon which said invention ismounted. Fig. 6, is a plan View oia portion of the carriage of a form oftypeu'riting machine coimnonly known the Remington, showing nipples uponwhich one form of my invention may be mounted. Fig. 7 is a perspectiveview ol a' modiiicd l'orm ol my said invention showing "parts ol' thecarriage ol a ditl'crcntForm ol' typewriting machine, whcreoii the sameis mounted. l 8, is a side elevation of onother modified i'orm of mysaid invention, showing the name plate of a third l'orm ol typewritinguuu'hine, whet-con the some is mounted.

in the drauings, l, is a body plate, which in one form of said inventionis provided with oppositely extending arms 2, 2, having thimblcsB,formed on or attached to their outer ends which thimbles are preferablyparallel with each other and directed at an angle to said plate. Formedon or attached to the rearward face of said plate, are stops 4 and i"spaced it suitable distance apart and formed on or secured to said rearface below the horizontal plane of the lower ends of said stops a foot5. Said stops and foot are preferably formed by striking loacluxnrdportions of metal from the said body plate. Above said stiips ispositioned. a pivoted plate 6 which pirotall coi'inoct'oi'l with saidbody plate, and is provided with suitable rearwardly turned side ribs orguides, as 6 and 6'; The pivotal connection botween said pivoted plateand said body plate is preferably eiicctod by forming an aperture Ametal forwardfrom said pivoted plate to form lingers 7 which are adaptedto extend through said aperture; said fingers are then clenched in said.body plate and stri lightly upon or over the forward face of said bodyplate The pivoted plate will t 111 be supported on the body plate bysaid lingers and said fingers will turn in said aperture. Positioned beteen said guides 6 and 6" and engaging the Lune is a scale bar 8extending upward beyond said plat s, and adapted in operative positionto rest at its lower end upon said foot Said s cale her is prcferablymade of springmctal, or is resilient, and its lower end ispreforahly'roundcd in Whole or in part, as at 8 so that when said scalebar is swung sideuise from erect to rccum bent'position, or vice versa,as it may be, as shown in blfllicll lines iii-Fig. l, together with saidpivot plate, said lower end of the scale bar will clcarsaid foot. Saidstops are sullicicnt to prevent the accidental turning or slipping ofsaid scale bar and pivoted plate from operative position, but one orboth of said stops are rcfcrablyshallow,- and when a moderate sidepressure is applied to the upper cud ol the scale bar, the loiver end ofsaid bar \iill spring or slip over said shallow stop 01' stops and thescale bar may be sr-guug down edgcwise to a horizontal position, asshown in broken lines in Fig. l, which latter position obviates thenecessity of removing the dcvicc from the typewriting machine\rl'ioncvcr it 1s desired to cover the n'iachine with a close littiughood as is commonly done engage said scale bar intermediate of its endswhen it is in horizontal position and to prevent the accidentaldisplacement of the some from such position by'gravity or vibration orvery light strains. When said scale bar is in horizontal position it mayhe slid longitudinally between said guides so as to eX tend'equally atopposite sides of the center of said ivoted plate and so that it willnot project eyond either end of the typewriting machine. The lower endof the scale bar is preferabl turned forwardly and upwardly upon itse fto form a shoulder as at 8 adapted in operation to bear against thelower edge of said pivoted plate and revent the accistops.

dental withdrawal of sai bar from said uides; but said shoulder may, ifdesired, be formed by striking forward a part of the metal from saidscale bar in manner similar to the referred-method of formin said ponsaid scale bar is shdably mounted a stop 10 of any suitable form,provided with a set screw 10 whereb the same maybe fixed at any suitablepre etermined point on said scale bar. 1

In mounting this device upon that form of typewriting machine commonlyknown as the Remington thecarriage of which is provided w1th twovertically dis osed socket posts or nipples as 11 and 11 ig. 6,

the thlmbles 3, 3, are set down over said nipples, which will hold mysaid device u(pon said carriage, said scale bar then exten I in upwardlyand rearwardly at an angle approximately as shown in said Fig. '5.

In order to mount said device upon that form of typewriting machinecommonly known as an Oliver the carriage of which is provided'with twoparallel frame bars as 12 and 12 I provide a base 13, Fig. 7, formthatform of ty ewriting machine commonly I roll on said name plate.

the arms 2, 2, and thimbles 3, 3, may, if desired, be omitted.

known as the Underwood the carriage of which is provided with a namelate as 14, Fig. 8, having a rolled u per edge, my device is'furthermodified by omitting all of said base except the breast plate and byforming an S shaped roll upon the lower end of said breast plate adaptedto engage the In this form also The scale marked on said scale rod ispreferably determined by marking on the rod the length of the coursefollowed by theisheet to be written from the type line, as X, of theplaten roll as 15 (shown in diagram) to various pointson the scalerodwith reference to sheets of different lengths, allowance being madefor a suitable margin. Thus for scaling a margin of one-half inch at thelower end of a thirteen inch sheet, 'the scale marl: 13 should be placedon the scale rod at a-disscale rod, said support clinc'd position.

tance of 12% inches from the t pe line of the roller following thecourse to he traveled by the sheet during the operation of writing. Theoperator knowing the length of the sheets used by him for variouspurposes adjust the stop 10 at the proper mark to allow for the desiredmargin at its foot. But other suitable methods of determining the scalemay be used as will be readily understood, and within the scope of myclaims, I do not therefore desire to restrict myself to the methoddescribed.

In using my device with said Remington machine, it is desirable to havea presser foot or roll to ress the paper, A, down above the laten rolland so prevent undue bulging or uckling of the sheet whichwouldotherwise tend on some occasions todestroythe approximate accuracy ofthe scale with, rela-' tion to the length of the sheet to be written.-81/ I have therefore provided the presser foot or roll 16 mounted on areci rocatable arm 17,

in which arm is formed t e'slots 18. and 19,

through which extend the screws 20 and 21 by which said arm is secured.to an inverted U-shaped base 22. Said base is adapted to straddle andrest upon a block 23 mounted on a frame bar 24'of the carriage of saidmachine and carrying a paper guide B, the func- I tions of which partthe arms 17 may er form. Said arm .17 is normally hel in yieldingforward position by a suitable light sp g, as25 bearing against said armand against said base.

My said invention may be further modified in details and minorparticulars within the I scope of certain of my claims.

What I claim is.
